Cloud & software engineering

Build it well.
Keep it running.

We build software and the cloud infrastructure it runs on. From a new product to a system already in production, we help with development, delivery and day-to-day operations. We work remotely with teams worldwide.

From the first build to the day-to-day running.

Software, infrastructure
and the work between.

You might need a complete product built, or help with one part of it. We work across applications, cloud infrastructure, software delivery and security.

01

Cloud Engineering

Architecture, migration & operations

We design cloud environments around your application and how you need to run it. That includes moving systems to AWS, managing infrastructure as code, and working through performance, cost and recovery requirements.

More about cloud engineering
  • Architecture & infrastructure design
  • Cloud migration & modernization
  • Infrastructure as Code
  • Containerized & serverless deployments
  • Performance & cost optimization
  • Backup, availability & disaster recovery
02

DevOps

Pipelines & production tooling

Manual releases and inconsistent environments make everyday engineering harder. We help your team automate delivery, manage containers and understand what’s happening in production.

More about DevOps
  • CI/CD pipeline implementation
  • Docker & Kubernetes
  • GitHub Actions & Jenkins
  • Infrastructure automation
  • Deployment architecture
  • Monitoring & observability
  • Production environment management
03

DevSecOps & Security

Access, code & configuration

We review applications, cloud configurations and delivery pipelines for security issues. The work includes access controls, secrets management, vulnerability scanning and OWASP-focused testing.

More about DevSecOps
  • Secure CI/CD & vulnerability assessment
  • Application & infrastructure security
  • IAM, access control & secrets management
  • Container & cloud security
  • Security scanning & remediation
  • OWASP-focused security testing
  • Cloud configuration reviews
04

Software Development

Web, mobile & desktop applications

Whether you’re building a SaaS product or updating an existing application, we work across the frontend, backend, APIs and database. We also handle the integrations your software needs to work with other systems.

More about software development
  • Full-stack web applications & SaaS
  • Backend systems & APIs
  • Mobile & desktop applications
  • Database architecture
  • Third-party integrations
  • Existing application modernization
05

AI Engineering

LLM integration & deployment

We connect AI models to applications, data and workflows. That can mean an AI voice agent that answers your business calls, adding an LLM feature, setting up retrieval-augmented generation (RAG), or deploying an AI application to the cloud.

More about AI engineering
  • AI voice agents for calls and bookings
  • AI / LLM application integration
  • AI-powered backend services
  • RAG infrastructure
  • API integrations & workflow automation
  • Cloud deployment of AI applications
  • Infrastructure for SaaS & AI products

Different industries.
Different pressures.

A fintech team worries about audits. An AI startup worries about response times and model costs. We shape the work around what your business is really up against.

SaaS & Technology

You need to ship new features every week without the platform falling over. We help with multi-tenant architecture, release pipelines and keeping cloud spend in line with revenue.

  • Multi-tenant AWS setups
  • CI/CD and safe releases
  • Cost and performance reviews

AI Startups

Getting a model to work in a notebook is one thing. Putting it behind an API that paying users depend on is another. We build the backend, retrieval and cloud setup around your AI features.

  • LLM and RAG integration
  • Scalable AI backends
  • Cost controls per request

FinTech

Money moves through your systems, so security and traceability are part of the product. We focus on access control, encryption, audit trails and infrastructure that’s easy to review. We’ve also built milestone escrow flows on smart contracts.

  • Security assessments
  • IAM and secrets management
  • Audit-friendly infrastructure

Healthcare Technology

Patient data raises the bar on privacy. We help you design environments with tight access rules, encrypted storage, clear logging and backups you can actually restore, so your compliance work has something solid to stand on.

  • Encrypted data and backups
  • Access logging and monitoring
  • Secure application reviews

Software Development Companies

Agencies and product studios bring us in when a client project needs cloud, DevOps or security depth that isn’t available in-house. We’re happy to work quietly in the background or side by side with your developers.

  • Extra DevOps capacity
  • Cloud setup for client projects
  • Security reviews before launch

The build is only
part of the job.

We also think about how you’ll release changes, manage access, investigate problems and keep costs under control. Those conversations start early.

Build

First, what does the application need to do?

We start with your requirements, then work through the application architecture, database and integrations. Decisions about deployment and security belong in these early conversations too.

The work involvedProduct & technical discoveryApplication & database architectureEngineering & integrations

These activities overlap. Security, deployment and operations inform the application as it’s being built.

Cloud engineering and software development

A multi-tenant SaaS product, deployed on AWS

TraceRoot helps teams investigate incidents properly, from the first problem statement through fishbone diagrams and five-why analysis to a final action plan. We built it as a multi-tenant SaaS application and took it to production on AWS.

The app runs in Docker containers on Amazon ECS, with PostgreSQL on RDS. Every tenant’s data is kept separate, sign-in uses JWT with role-based access, all traffic is encrypted with TLS and CloudWatch keeps an eye on the running services.

What we delivered
  • React frontend and Node.js API
  • ECS and RDS production setup
  • JWT sign-in and role-based access
  • PDF and CSV reporting
  • CloudWatch monitoring

DevSecOps and security

A security assessment of a SaaS and API environment

A client wanted to know how exposed their web application and APIs really were. We ran automated scans with OWASP ZAP and then checked the results by hand, so the final report only listed issues that were real.

The testing covered common OWASP risks, API configuration, authentication behaviour, security headers and what the application exposed to the outside world. Every finding was ranked by severity and handed over with clear steps to fix it.

What we delivered
  • Automated and manual testing
  • OWASP risk coverage
  • API and authentication review
  • Prioritized findings
  • Remediation guidance
